In this radio interview, Ayn Rand explains her theory of rights as a social application of morality, designed to ensure “those conditions of existence which are required by man’s nature for his proper survival.” The individual’s rights to life, liberty, property and the pursuit of happiness, she argues protect his ability to act on his own rational judgment, to choose his own values, and to keep the material product of his efforts. Rand addresses and rejects theories that rights are gifts from a supernatural power or from society. She also discusses the contradiction involved in asserting welfare rights to goods and services.
